Aquarium filter / Neon Tetras questions.?

I'm going to set up a 90 gallon tank soon ( right now I have a 55 gallon) with a big filter. But for the 90 gallon, I have two canister filters. Does it really need TWO canister filters? Its a Fluval 304. Also, I have neon tetras, mollies and a beta. Should I keep the big filter that hangs off the back on for water flow or is there a better, more visually pleasing way to make sure the water is oxygenated for them? Can the tetras get sucked up into the canister intake?
there are only 30 fish in the tank, mostly tetras. I doubt we will add very much more. No more than 40. But will two canisters alone, provide enough oxygen in the water for them? Also, I have unfortunately read that they often have leaks too. How can I prevent this?

your fluval 304 has a turn over rate of 2.8 times a hour that is not very good but running 2 of the same filters gives you a turn over rate of 5.7 that is pretty good running 2 of them would be good. i personaly have had this same filter and it had a problem of leaking around the seal so be careful and watch them close for leaks. to find out what size filter you need this is how it is done gallons of tank x 4 (how many times you want your water to go threw the filter a hour this is called turnover) 90 x 4 = 360 gph (this is called gph) your filters gph has to total up to 360 then your filter will work properly. you can never have to much filteration. on big tanks 55 or more i would use a canister filter much more better than hang on back filters imo.
